5 unit commercial strip, is this a deal?

[Jarred Sleeth]

Hey BP,

I was out yesterday doing some shopping and the owners of the store I was in approached me about selling their other location. I'm a frequent customer and they know I buy real estate which is why they asked. They own the building their other location is at. It's a 5 unit strip center in a good location with two nationally franchised tenants, their store, a hair salon that has been there for a long time, and in the process of signing on the last unit which will be a nail salon. They have owned the building since 1997, and it was on a 99 year ground lease with roughly 65 years remaining. 

I'm posting here in hopes of learning a little bit about this ground lease and what the pros and cons of such an investment would be.  I invest for the long term for cash flow. They are asking 500k which is about 100k/unit, and at that price it didn't seem outrageous or anything. It's not currently on the market, but they are older and are tired of dealing with it. I don't know all of the numbers for income/expenses yet, but I'd like to know if this kind of deal is common and if it would make sense before I sit down with them to get more details.

Does this sound like a deal to you? What would you do? They are motivated and as far as I know I am the only one looking so far.

Thanks!
